The rotary “volume” control determines the gain
setting, which ranges from ‘0.0dB’ (no output) to
’80.0dB’ (full output). This control does not function
like a typical volume: When you rotate the dial,
either clockwise to raise the volume or counter-
clockwise to lower the volume, you are actually
engaging a precision optical encoder which selects
very high quality metal-film resistors that the audio
signal passes through. The result is a proprietary
gain circuit, called M-eVOL2 that doesn’t degrade
the audio signal regardless of the setting, unlike all
potentiometer based circuits. Since this circuitry
operates in a fully balanced differential mode, no
noise is introduced to the audio signal.
Furthermore, there are no actual moving parts, so
this technology has a minimum life expectancy of
one million rotations.
The MOON 700i integrated amplifier provides a
range of five-hundred and thirty (530) unique
volume settings. This is achieved as follows: Within
the 0.0dB to 30.0dB range, you can increase and
decrease the volume in 1.0dB steps. From the
30.0dB to 80.0dB range, you can increase and
decrease the volume by either 0.1dB or 1.0dB steps;
By rotating the volume control slowly, the level will
change by 0.1dB increments. A quicker rotation will
change the volume in 1.0dB increments.
Note: To change the balance between the left and
right channels, please refer to the section “Remote
Control Operation”.
The “‡ Input ˆ” buttons allow you to choose which
input source you wish to listen to. The MOON 700i
dual-mono integrated amplifier has a total of five (5)
inputs; The first input is fully-balanced and uses
XLR connectors labeled B1. The next four (4) inputs
are single-ended and use RCA connectors labeled
S1, S2, S3 and S4. Assuming that you’re currently
listening to a source component connected to input
B1, the “ˆ” allows to sequentially scroll forward
through the available inputs from S1 to S4. The “‡”
button allows you to sequentially scroll backwards
from S4 to B1. Holding down either the “ˆ” or “‡“
button will allow only a single change of the selected
input. You must press the button again to select the
next or previous input.
The “Setup” and “OK” buttons are used for
programming the numerous software functions
available on this integrated amplifier. The next
section, entitled “Software Setup”, explains their
usage in detail.
Software Setup
The MOON 700i integrated amplifier includes
powerful software that allows you to configure it to
meet your specific needs. For each of the five (5)
inputs, you can assign a label to replace the factory
assigned name (i.e. B1, S1, etc.), assign a maximum
volume level of less than 80.0dB, create an offset
volume level ranging from –10.0dB to +10.0dB,
bypass the volume control (to exclusively use the
source component’s volume instead) and disable the
input completely when it’s not in use. As well, you
can assign any and all inputs to activate the 700i’s
12 Volt trigger , disable the front panel infrared
sensor and change the IR code set for use with a
universal remote control. Finally, there’s a facility to
reset all software settings back to their factory
defaults. Please refer to the accompanying quick
reference diagram for a snapshot of the entire Setup
menu layout.
When you are in Setup mode, there are five (5)
front panel items used to program this integrated
amplifier; The “Setup” button for navigating up and
down through the various menu levels, the rotary
volume control for scrolling through the available
choices within each programmable item, and the
“OK” button for confirming and saving your
selections.
What follows are step-by-step examples of how to
configure an input, assign the 12 Volt trigger and
reset the software back to the factory default. We
will begin by walking through all 5 available options
for the “B1” input:
